I have considered taking a certification course to teach English. I have only an AA degree in Electronics Technology, but am a native English speaker and have extensive work related world wide travel experience. Being from Texas, U.S.A., some might say I speak with a foreign accent.

I have reviewed several job listings here, particularly for China, and see that they all have age maximums. I am 67 years old, but hadn't considered that as a detrimental factor. Apparently others do.

"CaliRay" is now of 68. Too much older for a job, I think. I would be happy if he would reply about getting a job or not still now. But, he may get a job in some private institutions showing his previous experience and success. He must be great in mentality.

Many schools in Asia do prefer the young ones -- in part because they will put up with intolerable conditions, long hours, insensitive bureaucracy and more. Still, the more reputable and the desperate will consider us "older folks" because they know we are more responsible and have much more life and work experience to draw upon. Older teachers are (quite often) better teachers!

The law in most countries prohibits issueing work permits for those over a certain age and stipulates a BA as the minimum qualification. This is a pity because often those with lesser degrees are better teachers. As for age, life experience is often better than a piece of paper when it comes to knowledge.However, rules are rules so your best bet is online tutoring via Skype.

Your age is not the major factor if you are adventurous enough. Do you you know how to teach English? There's more to it than meets the eye. Try going for a CELTA course. Travel to the country you want to, then advertise yourself independently. As an independent qualified native speaking teacher, you will be in high demand and will beat all the competition, especially the language centres, who will wish they didn't have an age restriction.

Yeah, I would say there's a stigma after a certain age in Japan as well.
Which is kind of scary... as everyone will get older (myself included!)

But that's not to say there isn't good work either.
Older folks can often teach at universities, businesses, or community centers but those tend to be more part-time positions that you have to string together and schedule for yourself. Here it's unlikely a Jr. High, High School, or Language School will hire someone after their late 40's.
